We are working on the software development using vybrid processor. We are analyzing efficient way for data exchange between A5 and M4 core. We have data structure which contains variables of all the types (bool, int, short int etc). We would like to keep this structure in the shared memory and access the same structure in both A5 and M4 core. We are worried that the size of the structure might vary between A5 and M4 core since it is entirely 2 different cores.If the size differes due to structure alignment/padding , then this mechanism will not work

Please advise on this
